FFICEQ NEW ORLEANS, LOUISIANA, ASSIGYOR AND ROBERT H. SIMONS, OF NEIVOR- VESTlBULE-CAR.

SPECIFICATION forming part of Letters Patent No. 782,025, dated February'7', 1905.

Application filed June 29, 1904. Serial No. 214,614.

be it ltnown that I, JULEs ALLoU DHmtn eoturr, a citizen of the UnitedStates, and a resident of New Orleans, in the parish of Orleans andState of Louisiana, have invented a new and Improved vestibule-Car, ofwhich the following is a full, clear, and exact description.

My invention relates to the vestibules of cars. and more particularly tothose which extend the full width of the car and have the space betweenthe platform and outer door closed by atrap. In such a structure theordinary practice is to operate this trap from the inside before openingand after closing the door. the preparation for egress and ingressrequiring two distinct operations.

To furnish means for simultaneously operating the door and trap is theprincipal object of my invention: and with this end in view it consistsin the various features and combinations hereinafterdescribed andclaimed.

Reference is to be had to the acompanying d rawings, forming a part ofthis specification, in which similar characters of reference indicate;:orrespomling parts in all the figures.

Figure I is a perspective view of a portion of the end of avestilmle-carto which one embodiment of my invention is applied. Fig. 2 is a partialbottom plan view thereof, showing the door and trap partly opened. Fig.3 is a similar view illustrating another position of the elements. Fig.a is a vertical section showing the parts stilI further opened, and Fig.:3 is a bottom plan view in which the door and trap are fully opened.

L designates a car having a platform P and a vestibule structure Vextending over the steps S to the full width of the car, in whichvestibule there is a door D. Filling the space between the end of theplatform and the door when the latter is in its closed position is atrap, which is here shown in two sections 10 and II. The former or mainsection is secured to the end of the car by hinges 12 12, which permitit to be turned up against said car. the section 11 being pivotallymounted upon the section 10 by hinges 13 13. Both sections may besupported at their ends opposite the car by a ledge 14, while thesection 11 may receive further support by the manner of attachment ofthe hinges, which being upon the upper side bring the adjacent edges ofthe sections together and prevent their opening beyond horizontalalincment. The bottom of the door may be provided with a transversestrip or head 1%, extending beneath the trap and serving to close thespace between the elements against the entrance of air and dust.

Fastcncd to the end of the car beneath the trap is a plate 15, havingupper and lower flanges 15 extending toward one another and furnishingways in which moves a slide 16. This slide is connected with a plate 17,fixed to the door near the bottom beneath the. bead let by a linlt 18,which is articulated to the slide and plate by hinges 18. The. oppositeend of the slide is connected to the underside of the trap by a link 19through joints which are preferably universal in character, they beinghere shown as consisting of eyes 20, carried by the slide and by a plate202, secured to the under side of the trap, which eyes engage openingsin the ends of the link.

The section 11 of the trap is provided with a contact member, which ishere illustrated as a rotatable roll 21, mounted upon a spindle 21,extending across a recess 21". In the closed position of the trap theouter section 11 is held by its weight with the roll resting against aninclined contact-surface 22, which is here shown as a portion of a track23, extending over the surface of the door in substantially the arc of acircle, so that the roll may coact therewith throughout the movement ofthe elements, as will be hereinafter described.

Upon the end of the car, lying in the plane of the end of the track 23,is a horizontal track-section 24:, and below this is a shorter section25, with which the inner end of the trap-section 11 may contact.

Vhcn the 'estibule-door is closed, the parts will occupy the relativepositions illustrated in Fig. I of the drawings, the two trap-sectionsbeing in horizontal alinement and furnishing a continuous floor to thevestibule. When the door is opened, the pressure of the inclinedtrack-section against the roll causes the latter to ride up it, turningthe section 11 about its hinges at an angle to the companion section,this initial movement being permitted without the raising of thecompanion section by the play existing in the joints between the links,the slide,and the parts they connect; but as the door continues to openthe link which is connected with the slide causes said slide to move inits ways and by means of the link 19 raises the section 10 upon itshinges. Then as the inner end of the section 11 approaches the end ofthe car it strikes against the track 25, which tends to turn it upon itshinges into alinement with the section 10, bringing the roll 21, whichhas passed over the whole length of the track 23, into cooperation withthe track 24, over which it runs. Finally the track 23 contacts with thetrap at the adjacent edges of the sections and presses them back intoalinement against the end of the car, as is shown in Fig. 5 of thedrawings. \Vhen the door is closed, the links, acting through the slide,draw down the trap, the roll operating over the track 23, and as thedoor attains a position of complete closure the weight of the sectioncarries it down over the incline 22 into a horizontal position,completing the closure. In this manner the opening and closing of thevestibule-door either from the inside or outside automatically actuatesthe trap, greatly increasing the ease and convenience of operation.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination with a door, of a trap, and meansfor connecting the door and trap and extending beneath said trap wherebythey may be simultaneously operated.

2. The combination with a door, of a trap formed in sections, and meansfor connecting one section to the door, another section operating incontact with but movable independently of said door.

3. The combination with a door, of a trap formed in sections, means forconnecting one section to the door, means for inaugurating movement ofanother section, and a roll moun ted in the last-named section andcooperating with the door.

at. The combination with a door, of a trap formed in sections, means forconnecting one section to the door, means for inaugurating movement ofanother section. a track fixed to the door, and a roll mounted upon thelastnamed section and contacting with the track.

.5. The combination with a door having an inclined surface, of a trapformed in sections, means for connecting one of the sections to thedoor, and a contact member carried by another section and coacting withthe inclined surface.

6. The combination with a car, of a door and trap movable thereon, aslide mounted upon the car, and links connecting the slide with the doorand trap.

7. The combination with a car, of a door, a trap having two sectionshinged together, means for connecting the door and trap whereby they maybe simultaneously operated, means carried by the door for moving one ofthe trap-sections relatively to the other, and means carried by the carfor restoring the sections to their original relation.

8. The combination with a car, of a door, a trap having two sectionshinged together, means for connecting the door with the trap wherebythey may be simultaneously operated, means for moving one trap-sectionwith relation to the other, and tracks fixed to the door and car andwith which the trap may cooperate.

9. The combination with a car, of a door, a trap having two sectionshinged together, means for connecting the door with the trap wherebythey may be simultaneously operated, means for moving'one trap-sectionwith relation to the other, a contact member carried by the door, andtracks fixed to the door and car and with which the contact member maycooperate.

in testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
